The XP Power HHP650PS24 is a 780W AC/DC converter delivering a nominal 24V output. It operates from a wide input voltage range of 80-305 VAC with a power factor greater than 0.9, complying with EN61000-3-2 Class A harmonic limits. The converter achieves 85% typical efficiency and provides a power density of 8.2 W/in³.
Electrical features include remote sense compensating for 0.5V voltage drop, single-wire current sharing for parallel operation, and an uncommitted isolated optocoupler for remote on/off control. Protection features cover overvoltage (115-145% Vnom), overload (110-140% on V1), overtemperature with auto reset, and short circuit with constant current characteristic.
The unit operates over -40°C to +70°C with linear derating above 50°C at 2.5%/°C to 50% at 70°C. It meets EN55032 Class B conducted and Class A radiated emissions, and withstands surges per IEEE Std C62.41-1991 location category C1 (6kV, 3kA). Safety approvals include IEC60950-1 CB report, CSA 22.2 No. 609, UL508, and UL1604 Class I Division 2.
The input voltage range is 80-305 VAC, with output power derated 10% below 90 VAC.
The operating temperature range is -40°C to +70°C, with linear derating above 50°C at 2.5%/°C to 50% at 70°C.
It includes overvoltage protection (115-145% Vnom, recycle input to reset), overload protection (110-140% on V1), overtemperature protection with auto reset, and short circuit protection with constant current characteristic.
The typical efficiency is 85%.
